CIGARETTE-MAKING MACHINERY.

Application filed December 2, 1926, Serial No. 152,29 and in GreatBritain December 21, 1925.

This invention is for improvements in or relating to cigarette makingmachinery and more particularly to a method and means of severing corkor like tips from a travelling each severed tip is arranged upon thetravelling web of cigarette paper with two of the edges thereofarranged'parallel to the edges of the travelling web of cigarette paperand the remaining two edges arranged substantially normal'to the saidedges.

According to the present invention there is provided a method ofsevering cork or like tips from a travelling web of material andapplying the same to a travelling web of cigarette paper wherein theleading edge of the web of cork or the like is yieldingly held inengagement with the travelling web of cigarette paper as a tip is beingsevered.

Further the present invention consists of a device for severing cork orlike tips from a travelling web of material andapplying the same to atravelling web of cigarette paper which comprises means adapted to'holdthe 7 leading edge of cork or the like in yielding engagement with theweb of cigarette paper as a tip is being severed.

The invention is more particularly de scribed with reference to theaccompanying drawing which illustrates a section of a tip ping andprinting panel embodying the pres ent invention.

Referring to the drawing a web of cork 1 is continuously fed by rollers1 and 1" to a rotary cutting blade 2 ofthe character described in myco-pending U. S. Patent No. 1,700,906.

Arranged in advance of the said cutting device and in the path of thetravelling web of cork is a guide roller 3 around which is adapted totravel a web of cigarette paper 4. The roller 3 is arranged so that thetangential plane common to the rotary cutting blade 2 and the roller 3is located in a horizontal direction.

Mounted above the roller 3 is a pressure roller 5 preferably constructedof a greater I diameter than the roller 3 and arranged in such a mannerthat a portion of the cylindrical face thereof extends below thetangential line which-joins the edge of the rotary cutting blade 2 withthe surface of the roller 3 and in advance of the roller 3 whenconsidered in relation to the direction of movement ofthe leading edgeof the travelling web of cork. 1 A

The roller 5 preferably has its rotational axis iixed, whereas therotational axis of the roller 3 ismovable about a pivot 6 towards andaway from the line joinin 'the axes of the roller 5 and the rotarycutter 2. ad-' justably mounting the roller 3 in the manner hercinbeforedescribed it is possible to vary the length of the path betweenthe'eutting mechanism and the point where the leading edge of'the corkis gripped between the travelling web of cigarette paper and thepressure I roller 5.

Further, due to the fact that the cylindrical surfaces of the'rollers 3and 5 are spaced apart from one another, the leading edge of thetravelling webof cork is gripped between the travelling web of cigarettepaper and the pressure roller 5 and is held merely by the friction whichis produced between the roller 5 and the cork by the pressure of thetravelling web of cigarette paper 4:. This frictional grip. may bevaried by adjusting the position of the roller 3 relatively to theroller 5.

According tothis invention it will be found that the positions of therollers 3 and 5 may be adjusted to ensure that the cutting mechanismsevers a tip from the travelling web of cork immediately the leadingedge. of the Web is gripped between the pressure roller 5 and thecigarette paper 4. Further should the leading edge of the cork webvbefed betweenithe cigarette paper and the'pressure roller 5 prior to'thecutting-operation, there to slip over the cigarette paperuntil thecutting operation is effected without deflecting the Web of cork, thefriction, however, is sufiicient to grip the tip once it has beensevered from the web and feed the same for ward. I

By arranging the two rollers 3 and 5 in the f mannerhe'reinbeforedescribed so that the leading edge of the web 1 is yieldingly heldduring the cutting operation all possibility of the tip being movedrelatively to the web whilst it is beingsevered is eliminated and eachtip is applied to the web with two edges thereof arranged parallel withthe edges of the web and the other two edges arranged at right anglesthereto.

Preferably the pressure roller engages with a roller 7 which ensuresthat as the web of cigarette paper 4; is fed forward the web 90 existssufficientslip to permit the web of cork is heldin surface contact withthe pressure roller 5. The provision of the roller 7 also ensures thatthe severed tip cannot move relatively to the web of cigarette paper andfurther assists in securely applying the tip to the web.

WVhat I claim as my invention and desire to secure by Letters Patentis 1. A device for severing tips from a travelling web of tippingmaterial and applying the same to a travelling web of cigarette paperwhich comprises in combination means for feeding a web of tippingmaterial continuously in the direction oi movement of the cigarettepaper, rotatable cutting mocha nisin adapted to sever a tip from thesaid web and a" pair of rollers mounted one on either sideot the web ofcigarette paper and arranged so that the said web engages with theperiphery of each roller in such a manner that the leading edge of thetipping material is frictionally held between one roller and thecigarette paper so as to permit the same to slip relatively to thecigarette paper until a tip is severed therefrom, whereupon the tip isgripped between the said roller and the cigarette paper so as to be fedforwardly by the same.

2. In a device for severing tips for cigarettes from a travelling web oftipping material the combination with cutting means, of a roller havingits peripheral surface disposed tangentially of the path of movement oi.the web, a relatively smaller roller having its surface disposed inproximity to the surface of the larger roller said rollers being adaptedto trictionally grip the web of material from the cutting means, andmeans for supporting said smaller roller for adjustment along theperiphery of the first mentioned roller whereby the cutting and grippingoperations maybe co-ordinated.

In testimony whereof I hereunto my signature.
